CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to and the benefit under 35 U.S.C. §119(e) of U.S. Provisional Application No. 61/444,597, filed on Feb. 18, 2011. The entire content of that application is hereby incorporated by reference herein.

BACKGROUND

1. Field

The present invention relates to an apparatus, method and/or system for applying a protective material or layer to a surface of a device. For example, the present invention may allow a user to apply a protective material or layer to the surface or screen of an electronic device.

2. Description of Related Art

Electronic devices such as cellular phones, portable tablet computers and the like are gaining widespread popularity. For example, the Apple® iPhone® is estimated to reach 100 million users by the end of 2011. In addition, almost 15 million Apple® iPads® have been sold to date. The sheer volume of electronic devices sold by other major competitors such as Motorola®, Samsung®, HTC®, etc. only further confirms that consumers find these products very desirable. It should not come as a surprise that these same consumers want to protect their products from accidental denting, scratching or otherwise damaging these electronic devices. Accordingly, manufacturers have produced different cases, protective films and the like to help the consumer keep their electronic devices safe.

However, with the progress of touch-based screens for operating these electronic devices, thick cases might not be suitable, as these cases may prevent the user from operating the device. Accordingly, many manufacturers are now producing clear films that keep, for example, the display of the electronic device clean while at the same time protecting the screen from accidental damage such as scratching.

Despite the benefits that these films or screen protectors provide, many drawbacks remain in this relatively new technology. For example, many of these protectors require the use of a wet fluid solution to enable the film to adhere to the electronic device. Using a wet fluid solution is messy, requires a lot of work by the user to “squeegee” the excess out, and might not eliminate all annoying air bubbles immediately. Indeed, many of these products warn that 24-48 hours may be needed before the user can effectively determine if the trapped air bubbles are going to disappear. In other words, some consumers may have to wait for days before determining if the film was applied correctly. To some consumers, this long wait is annoying and may reduce the enthusiasm of an otherwise exciting moment of obtaining a cutting-edge electronic device. Moreover, the electronic device might not be functional until the solution dries out in 24-48 hours. Alternatively, the consumer might not want to risk using the device in fear during this time period as he or she may believe that usage may impact the film prior to drying of the wet fluid solution.

What is needed is an applicator that eliminates the drawbacks above and allows a user to apply the protective film effectively for use without waiting for the protective film to dry and/or waiting for the air bubbles to disappear.

SUMMARY

Devices, methods and systems are provided to apply a protective film on a surface of an electronic device which reduces or eliminates air bubbles and eliminates the waiting time usually required when using a wet fluid solution.

In one embodiment, a roller apparatus may be used in a protective film application process to eliminate air bubbles and assist the user in applying the film to the electronic device correctly. The roller apparatus may include a carriage or housing, one or more rollers coupled to or integrated with the housing and a splitter configured to separate the protective film from a backing material during the application process.

In one embodiment, the roller apparatus may be configured to be maneuvered into position with the splitter between the exposed portion of the protective film and the backing with the roller portion of the roller apparatus trailing behind. As the user pulls the roller apparatus from a first edge of the electronic device to a second edge of the electronic device, the protective film may be removed from the backing, applied to the device, and any air bubbles may be immediately squeezed out such that in one motion the protective film may be applied to the electronic device without the use of a wet fluid solution.

In one embodiment, a method of applying the protective film to an electronic device is provided. For example, first, a user may remove one edge of the protective film from a backing and line up the removed edge of the protective film with the corresponding edge of the electronic device. No wet fluid solution is sprayed on or applied to the surface or screen of the electronic device. Next, the roller apparatus may be maneuvered into position with the splitter between the exposed portion of the protective film and the backing with the roller portion of the roller apparatus trailing behind. As the user pulls the roller apparatus from a first edge of the electronic device to a second edge of the electronic device, the protective film may be removed from the backing, applied to the device, and any air bubbles may be immediately eliminated such that in one motion the protective film may be applied to the electronic device without the use of a wet fluid solution.

In one embodiment, for example, where the protective film includes an overlay portion intended to be pressed down on the sides perpendicular or orthogonal to the main surface, the user may press the protective film down on the intended, corresponding areas and use the roller portion of the roller apparatus to further press down on the protective film.

In one embodiment, a roller apparatus may include an integrated stand for propping up or holding the electronic device. In a first operational configuration, the roller apparatus may be used in a protective film application process to eliminate air bubbles and assist the user in applying the film to the electronic device correctly. In a second operational configuration, the roller apparatus may be used as a stand for propping up the electronic device. The roller apparatus may include a carriage or housing, one or more rollers coupled or integrated with the housing and a stand portion for propping up the electronic device.

DETAILED DESCRIPTION

Apparatus, systems and/or methods that implement the embodiments of the various features of the present invention will now be described with reference to the drawings. The drawings and the associated descriptions are provided to illustrate some embodiments of the present invention and not to limit the scope of the present invention. Throughout the drawings, reference numbers are re-used to indicate correspondence between referenced elements.

FIG. 1 illustrates a roller apparatus 100, an electronic device 135 and a film 150. The roller apparatus 100 may be used to apply the film 150 to a surface of the electronic device 135. The film 150 may protect the electronic device 135 from damage (e.g., scratches) and/or smudges. As shown, the roller apparatus 100 may have a width wider than the width of the electronic device 135 and the film 150. In this manner, the roller apparatus 100 may be configured to apply films of varying sizes onto devices of varying sizes. In addition, the roller apparatus 100 may be configured to apply the film 150 to a device with a curved surface (not shown). In one embodiment, the roller apparatus 100 may be increased in size or decreased in size (along with the appropriate proportions) for usage with significantly larger films and devices (e.g., a tablet PC).

FIG. 2A illustrates one embodiment of a roller apparatus 200. As shown, the roller apparatus 200 may include a roller base or carriage 205, a first or front roller 210, a second or back roller 215, a mid-bar 220, a first or left splitter 225 and a second or right splitter 230. The roller base 205 may be constructed out of a rigid material such as a plastic, a metal, a wood and the like. The roller base 205 is configured to provide structural support for the roller apparatus 200. In addition, the roller base 205 may be sized to be easily manipulated and graspable by a user's hand. The roller base 205 may be configured to hold the first roller 210 in place and allow the first roller 210 to “roll” or rotate about a longitudinal axis created by the roller base 205. In one example, the roller base 205 may be structured to include a first rod member (not shown) spanning the entire length of the first roller 210, thereby forming an axis for the first roller 210 to rotate about. The first roller 210 is configured to rotate and apply physical pressure on a film (e.g., film 150 of FIG. 1) in operation. The first roller 210 may be separated from the mid bar 220 by a first roller gap 235 and may be further separated from the first splitter 225 and the second splitter 230 by a splitter gap 245. These gaps (e.g., the first roller gap 235 and the splitter gap 245) may serve as structural openings to allow the first roller 210 to rotate freely. The second roller 215 may be a redundant pressure applicator and may be substantially the same size as, and substantially parallel to the first roller 210. The first roller 210 and the second roller 215 may be separated by a mid bar 220. The mid bar 220 may connect the two ends of the roller base 205 and provide the entire roller apparatus with stability. In addition, a gap 240 may exist between the mid bar 220 the second roller 215 to allow the second roller 215 to rotate freely. The first splitter 225 and the second splitter 230 may lie along the same plane and may be slightly curved. The splitters 225 and 230 may be configured to be rigid and may function to separate an adhesive portion of a film (e.g., film 150) from its non-adhesive backing during the application process.

FIG. 2B is a perspective view of the roller apparatus 200. In one embodiment, the roller apparatus 200 may be configured to function as a film applicator for phone-sized devices and may have a length of 1-2 inches, a width of 2-4 inches, and a height of 0.5-1 inch. In one embodiment, the roller apparatus 200 may be configured to function as a film applicator for tablet-sized devices and may have a length of 1-5 inches, a width of 8-12 inches, and a height of 0.5-2 inches. Other dimensions are also possible depending on the size of the device to be protected and/or depending on the size of the film to be applied.

FIG. 2C is a side perspective view of the roller apparatus 200. As shown, the rollers 210 and 215 may include inner cores 255 and 260, respectively. In addition, the rollers 210 and 215 may include outer cores 265 and 270, respectively. In one embodiment, the outer cores 265 and 270 may be configured to “flatten” at the point of contact and thereby providing pressure in a more uniform and distributed manner, efficiently eliminating air bubbles. The outer cores 265 and 270 may be configured to return to its original configuration when not pressed to the surface of the device (e.g., electronic device 135).

In one embodiment, the mid bar 220 may be curved or straight, and may have a length substantially equivalent to the length of the rollers 210 and 215, thereby joining the two ends of the roller base 205. Additionally, the mid bar 220 may be configured to have a width shorter than a diameter of the outer cores 265 and 270. In this manner, the mid bar 220 provides structural support to the roller apparatus 200 without contacting the film (e.g., film 150) or the device (e.g., electronic device 135) during the application process.

In one embodiment, the splitters 225 and 230 may be located adjacent to the first roller 210. The splitters 225 and 230 may jut inward from the roller base 205 so as not to extend the footprint of the roller apparatus 200. In addition, the splitters 225 and 230 may function to remove the non-adhesive backing from the adhesive portion of the film (e.g., film 150) during an application process. While shown to be two, distinct parallel elements, the splitters 225 and 230 may be joined together (e.g., by extending the splitters 225 and 230 towards one another) and/or may be constructed as one piece. The splitters 225 and 230 may be constructed out of any material with sturdiness sufficient enough to separate and remove the adhesive portion of the film (e.g., film 150) from a non-adhesive backing. In one embodiment, the splitters 225 and 230 may be curved and formed in the shape of a “C” as shown in FIG. 2C. The curvature (“C” shape) of the splitters 225 and 230 may advantageously increase the ease of by which the non-adhesive backing from the adhesive portion of the film (e.g., film 150) is removed. However, other configurations are possible. For example, a “letter opener” configuration where the splitters 225 and 230 include tapered edges may be utilized.

While described in FIG. 2C to have inner cores 255 and 260, certain embodiments of the roller apparatus 200 might not include inner cores 255 and 260. In one embodiment, the roller apparatus 200 may comprise any number of rollers (e.g., one roller—by removing the second roller 215, three rollers—by extending the width of roller base 205 and adding a third roller, etc.) In one embodiment, the roller apparatus 200 may comprises two parts, a roller (e.g., the first roller 210) and a base (e.g., the roller base 205), wherein the base may include an integrated mid bar (e.g., mid bar 220) and a splitter (e.g., splitters 225 and 230).

FIGS. 2D, 2E and 2F show other various views of one embodiment of the roller apparatus 200.

FIG. 2G illustrates a cross-sectional view of the first roller 210. All principles of the first roller 210 discussed herein may be equally applicable to the second roller 215. As shown, the outer core 265 may wrap the entirety of the inner core 255. In addition, the inner core 255 may have a substantially smaller diameter than the outer core 265. In one embodiment, the inner core 255 may be constructed out of a rigid material such as metal, wood, a hard plastic, etc. The outer core 265 may be constructed out of a different, non-rigid or semi-rigid material such as a rubber, a soft plastic or a polymer. In one embodiment, the material used to construct the inner core 255 may be the same as the material used to construct the outer core 265. However, in one embodiment, the densities of the material may be different. For example, the materials used to construct the outer core 265 may be less dense and/or have a lower durometer rating. By having a softer outer core 265, the roller apparatus 200 may be able to press the film (e.g., film 150) onto the device (e.g., electronic device 135) without causing surface damage. The softer material of the outer core 265 also helps to more effectively and advantageously remove the air bubbles between the film 150 and the screen of the electronic device 135.

Turning to FIG. 3A, an operation of the application process will now be discussed. As shown, a user may apply part of an adhesive portion 355 of a film 350 by removing a part of the backing portion 360 of the film 350 and lining up the adhesive portion 355 to a surface (e.g., a screen) of an electronic device 335. The roller apparatus 300 might not be used in this initial set-up step.

Next, as shown in FIG. 3B, the roller apparatus 300 may be configured and placed into position for operation. More particularly, the roller apparatus 300 may be placed on top of the film 300 and electronic device 335 with the splitters 325 and 330 between the adhesive portion 355 and the backing portion 360.

Once the roller apparatus 300 is in position, the user may place one hand on the electronic device 335 (for stability) and use the other hand to push (and roll) the film 350 onto the surface of the electronic device 335 by moving the roller apparatus 300 in a downward direction 380. As the roller apparatus 300 moves in the downward direction 380, one or more rollers 310 and 315 press the adhesive portion 355 of the film 350 onto the electronic device 335 and squeeze out any air bubbles that may be trapped between the film 350 and the electronic device 335. Contemporaneously, the splitters 325 and 330 provide a guide for the film 350 (i.e., “lead the way”) and remove the backing portion 360 of the film 350, thereby progressively providing more of the adhesive portion 355 of the film 350 for the rollers 310 and 315 to press down on.

After the roller apparatus 300 is pulled through, across or over the length of the electronic device 335, the adhesive portion 355 of the film 350 may be pressed onto the electronic device 335 and the user does not have to perform any other functions with respect to the surface with the applied adhesive portion 355.

Depending on the design of the film 350, this may conclude the application process. However, in certain embodiments, where the film 350 includes “overhanging” portions, the user may simply press these portions down onto the sides of the electronic device 335 to conclude the application process.

In this manner, the user does not have to use a squeegee, wet solution, etc. to remove the air bubbles or to apply the adhesive portion 355 of the film 350 onto the electronic device 335 and the entire application process may be improved with respect to, for example, cleanliness, ease of use and convenience.

FIG. 4A illustrates one embodiment of a roller apparatus 400. The roller apparatus 400 may include an apparatus body 405, a first roller 410 inserted into the apparatus body 405 and held in place by via hole 425 (and its paired hole—not shown). The roller apparatus 400 may also include a second roller (not shown) held in place by hole 430 (and its paired hold—not shown). The roller apparatus 400 may also include a splitter bar 415 and a mid bar 420. The mid bar 420 may be configured to span the length of the first roller 410 and may provide structural support to the roller apparatus 400.

FIG. 4B illustrates how the roller apparatus 400 may be used to apply a protective material 450 onto a device 435. The splitter bar 415 may be used to split or separate an adhesive portion of a protective material 450 from a non-adhesive backing during the application process. As shown, the roller apparatus 400 may be placed on the device 435 with the protective material 450 wedged between the first roller 410 and the electronic device 435. As the roller apparatus 400 is moved along the surface of the electronic device 435, the splitter bar 415 exposes the adhesive portion of the protective material 450 prior to the first roller 410 pressing the adhesive portion of the protective material 450 down onto the surface of the electronic device 435. In addition, the non-adhesive backing is removed during this process.

FIG. 5A illustrates one embodiment of a roller apparatus 500. The roller apparatus 500 may include a body 505, a first roller 520, a second roller 515, a splitter 510, a first pressing surface 525 and a second pressing surface 530. In one embodiment, the roller apparatus 500 may be constructed as one integrated piece. By integrating the first roller 520 and the second roller 515, along with the splitter 510 into the body 505, additional structural components may be eliminated. In one embodiment, the first roller 520 and the second roller 515 may be rod members that might not rotate. In another embodiment, the first roller 520 and the second roller 515 may be rotatable members.

FIG. 5B illustrates how the roller apparatus 500 may be used to apply a film 550 onto a device 535. As shown, the roller apparatus 500 may separate a top non-adhesive portion of the film 550 from the adhesive bottom portion of the film 550 as the user presses on the first pressing surface 525 and the second pressing surface 530 while moving the roller apparatus 500 along the length of the device 535. During such an operation, the splitter 510 may separate the adhesive and non-adhesive portions of the film 550 while the rollers 520 and 515 may apply the adhesive portions of the film 550 to the surface of the device 535. In this embodiment, the device 535 may be sandwiched or be located between the first roller 520 and the second roller 515. The first roller 520 may contact the film 550 (as shown in FIG. 5B) on a first surface (e.g., a screen) of the device 535 while the second roller 515 may contact a second surface (e.g., a backing) of the device 535.

FIG. 6A illustrates a roller apparatus 600, an electronic device 635, a film 650 and an optional film tab 695. The roller apparatus 600 may be used to apply the film 650 to a surface of the electronic device 635. In one embodiment, the film tab 695 may be used to improve the ease of applying the film 650 as further discussed below.

FIG. 6B illustrates one embodiment of how the roller apparatus 600 may appear when mounted on the electronic device 635, for example, during a film application process. As shown, the roller apparatus 600 may have a width wider than the width of the electronic device 635. In this manner, the roller apparatus 600 may be configured to apply films of varying sizes onto devices of varying sizes (e.g., a tablet PC). In addition, the roller apparatus 600 may be configured to apply the film 650 to a device with a curved surface (not shown).

However, distinct from the first operation configuration, the roller apparatus 600 may be utilized in a second operation configuration to hold, secure, prop or otherwise position the electronic device 635 such that it may be easier for a user to view and/or use the electronic device 635. For instance, the roller apparatus 600 may be flipped over to a second operation configuration and rest on a flat surface and the like to prop up the electronic device 635 and improve viewing angles of the electronic device 635 to a user. In this manner, the roller apparatus 600 may have continued utility even after a film (e.g., film 650) is applied by the roller apparatus 600 to the electronic device 635. As shown in FIG. 6C, the electronic device 635 sits in an upright manner within a cavity of the roller apparatus 600. In one embodiment, the cavity is defined to be a space between a front bar and a first roller.

FIG. 6D illustrates a side view of the roller apparatus 600 with the electronic device held in an upright manner. As shown in FIG. 6D, the electronic device 635 may sit angled while still being upright. By varying the width of the cavity (i.e., distance between the front bar and the first roller), the positioning of the stand edge and the like, the viewing angle may be adjusted between 90 degrees and 135 degrees. For example, as shown in FIG. 6D, the electronic device 635 may be held at an angle of 120 degrees as measured between a table surface and a viewing surface of the electronic device 635.

FIGS. 6E-6G illustrate one example of how the roller apparatus 600 may be utilized to apply the film 650 onto a surface of the electronic device 635. As shown in FIG. 6E, the tab 695 may be applied (and may adhere) to the film 650 and held in a preliminary application position by a user's hand near the surface of the electronic device 635. The tab 695 may function to aid the user in lining up the film 650 with the electronic device 635 and simplifying the application process since the user may be able to handle a portion of the tab 695 without worrying about whether the film 650 will adhere to the user's fingers during the application process. The roller apparatus 600 might not be engaged at this stage. In one embodiment, the tab 695 may be pre-installed on the film 650 for the consumer's convenience.

Next, as shown by FIG. 6F, a portion of the adhesive portion 655 of the film 650 has been separated from a portion of the non-adhesive film backing 660, and has been pressed onto the surface of the electronic device 635. At this point of the film application process, the user may retrieve the roller apparatus 600. The user may then utilize the roller apparatus 600 and press the adhesive portion 655 of the film 650 to the surface of the electronic device 635 with one hand while moving the roller apparatus 600 in a length-wise direction. Immediately proceeding the moment when the roller apparatus 600 presses one section of the adhesive portion 655 of the film 650 onto the surface of the electronic device 635 to remove any air bubbles, the user may remove a corresponding section of the non-adhesive film backing 660 with the other hand in preparation. In this manner, the adhesive portion 655 of the film 650 may be applied to the surface of the electronic device 635. In addition, any air bubbles between the adhesive portion 655 and the surface of the electronic device 635 resulting from the application process may be removed or squeezed out by the roller apparatus 600 being pressed and maneuvered.

FIG. 6G illustrates an example of how the user may utilize the roller apparatus 600 to apply the film 650 to the surface of the electronic device 635 while removing any air bubbles. Once the adhesive portion 655 of the film 650 is applied to the surface of the electronic device 635, the tab 695 may be removed by peeling (not shown) it from the film 650. In this quick and efficient manner, the application process may be completed.

FIG. 7A illustrates an embodiment of a roller apparatus 700 with an integrated stand. The roller apparatus 700 may be an embodiment of the roller apparatus 600 of FIG. 6. As shown, the roller apparatus 700 may be in a first operational position with rollers 710 and 715 in contact with the flat surface beneath it (e.g., table). The roller apparatus 700 may include a body or carriage 705 configured to provide structural support for the rollers 710 and 715. The carriage 705 may include attached or integrated handle portions 775, a mid bar 720 and two contact edges 780 and 785 separated by the rollers 710 and 715. The rollers 710 and 715 may include inner and outer cores 755, 760 (shown in FIGS. 7B and 7C), 765 and 770). The carriage 705 may also include a device insertion portion 795 for insertion of the electronic device (e.g., electronic device 635). However, the device insertion portion 795 may be intended for usage when the roller apparatus 700 is flipped over, as shown in FIG. 7B.

In one embodiment, the handle portions 775 may be configured to allow a user to press down on the handle portions 775 to transfer pressure onto the rollers 710 and 715 during a protective film application process. When the user presses down on the handle portions 775 and maneuvers the roller apparatus 700 along the length of a protective film (e.g., film 650), a force may be transferred to the rollers 710 and 715, which in turn applies a pressure to the protective film (e.g., film 650) resulting in adherence of the film (e.g., film 650) to a surface (e.g., a screen) of the electronic device (e.g., electronic device 635). In addition, any air bubbles may be eliminated due to the pressure applied by the rollers 710 and 715.

The carriage 705 may be constructed out of a rigid material such as a plastic, a metal, a wood and the like. In addition, the carriage 705 may be sized to be easily graspable and manipulated by a user's hand. The carriage 705 may be configured to hold the first roller 710 in place and allow the first roller 710 to “roll” or rotate about a longitudinal axis created by the carriage 705. In one example, the carriage 705 may be structured to include a rod member (not shown) spanning the entire length of the first roller 710, thereby forming an axis for the first roller 710 to rotate about. In another example, the carriage 705 may include two insertion portions opposite each other for inserting a rotational member of a first roller 710.

The first roller 710 may be configured to apply physical pressure on a film (e.g., film 650) in operation. The second roller 715 may be a redundant pressure applicator and may be substantially the same size as, and parallel to the first roller 710. The first roller 710 and the second roller 715 may be separated by a mid bar 720. The mid bar 720 may connect the two ends of the carriage 705 and provide the entire roller apparatus 700 with stability. In addition, gaps between the mid bar 720 and the rollers 710 and 715 may allow the rollers 710 and 715 to rotate freely without contacting the mid bar 720.

In one embodiment, the roller apparatus 700 may be configured to function as a film applicator for phone-sized devices and may have a length of 1-2 inches, a width of 2-4 inches, and a height of 0.5-1 inches. In one embodiment, the roller apparatus 700 may be configured to function as a film applicator for tablet-sized devices and may have a length of 1-5 inches, a width of 8-12 inches, and a height of 0.5-2 inches. Other dimensions are also possible depending on the size of the device to be protected and/or the size of the film to be applied.

In one embodiment, the mid bar 720 may be curved or straight, and may have a length substantially equivalent to the length of the rollers 710 and 715, thereby joining the two ends of the carriage 705. Additionally, the mid bar 720 may be configured have a width shorter than a diameter of the outer cores 765 and 770. In this manner, the mid bar 720 provides structural support to the roller apparatus 700 without contacting the film (e.g., film 750) or the device (e.g., electronic device 735) during the film application process.

In one embodiment, the contact edge 780 may be raised and further away from the flat surface (e.g., the table) than, for example, the rollers 710 and 715 when the roller apparatus 700 is positioned as shown in FIG. 7A.

As shown in FIG. 7B, when the roller apparatus 700 is flipped over, the contact edge 780 raises the rollers 710 and 715 off a flat surface (e.g., a table) and also orients the device insertion portion 795 such that insertion and propping of the electronic device (e.g., electronic device 635) is possible. As more clearly shown in FIG. 7C, when the roller apparatus 700 is in this position, the second roller 715 may be raised off the table and may allow for the electronic device (e.g., electronic device 635) to rest on an outer core 770 of the second roller 715. More particularly, the electronic device (e.g., the electronic device 635) may be contacted on a first surface by the second roller 715 and contacted on a second surface by the stand portion 790 as it sits within the insertion portion 795. In one embodiment, the stand portion 790 may be a flat panel having a length substantially similar to a length of the first roller 710 and the second roller 715. As shown, the stand portion 790 may be offset from the first roller 710 and the second roller 715. In other words, the stand portion 790 may be separated from the first roller 710 and the second roller 715 by a gap constituting the device insertion portion 795.

FIG. 7C is a side perspective view of the roller apparatus 700 in its second operation configuration. As shown, the rollers 710 and 715 may include the inner cores 755 and 760, respectively. In addition, the rollers 710 and 715 may include the outer cores 765 and 770, respectively. In one embodiment, the inner cores 755 and 760 may be constructed out of the same material (e.g., a rigid material such as metal, wood, and a hard plastic). Similarly, the outer cores 765 and 770 may be constructed out of the same material (e.g., rubber, a soft plastic, an encapsulated gel, etc.) or a softer material. In one embodiment, the material used to construct the inner cores 755 and 760 may be the same as the material used to construct the outer cores 765 and 770. However, the densities of the material may be different. For example, the materials used to construct the outer cores 765 and 770 may be less dense and/or have a lower durometer rating. By having softer outer cores 765 and 770, the roller apparatus 700 may be able to press the film onto the device (e.g., electronic device 635) without damaging the surface. In one embodiment, the outer cores 765 and 770 may be configured to “flatten” at the point of contact and thereby providing pressure in a more uniform and distributed manner, efficiently eliminating air bubbles. The outer cores 765 and 770 may be configured to return to its original configuration when not pressed to the surface of the device (e.g., electronic device 635).

FIG. 7D and FIG. 7E show other various views of one embodiment of the roller apparatus 700.
